Compare concentrated and distributed change

Ordinary wear may extend along an exposed region, whereas a single puncture or burn-like feature is more localized. Both can coexist, and an impact or other heat source can create another localized mark. Describe the feature without automatically naming a lightning strike. Do not infer internal path, temperature or damage depth from the size of the visible opening or its dark outline.

Connect the surface with the wider event

Check whether credible lightning timing aligns with the first observation and any related equipment event. The actual blade protection arrangement must be established from supplier evidence, not assumed from a metal-looking spot in an image. A specialist may need to assess the surrounding composite and associated protection paths. Surface repair alone cannot establish that every function potentially involved in the event remains acceptable.

If an earlier image shows an erosion patch at the same location, compare what changed during the suspected event. A new puncture within old wear should not be described either as entirely pre-existing or entirely new without separating those observations.

Choose examination before restoration

Ask whether the defect is limited to the visible region and what inspection can bound any concealed damage. The repair scope should reflect the assessed material condition and the documented blade arrangement. Do not fill, sand or paint the feature before the assessment plan is agreed. No MARSTON receptor design, lightning certification or permissible puncture size is asserted here; the relevant supplier and qualified reviewers must determine the next action.
